Cross module inline, LDC, dub dependencies.
OK so I am using the intel intrinsics library, I ws just copying it into my source tree. So in the interests of automation I added it as a dependency in dub, but now my code is anywhere up to 3 times slower. So I figure maybe as its being compiled as a library, it's not getting inlined because i remember something about LDC not doing cross module inlining unless you tell it to.. So I pass "-enable-cross-module-inlining" to LDC, and then I get this... source\dg2d\misc.d(11,15): Error: module `inteli` is in file 'inteli.d' which cannot be read so i'm guessing LDC needs the source file to do the cross module inlining? Any ideas what I should do?

If it does find out where and why they are spawned.

Re: CT BitArray

I am guessing these are filled in by compiler intrinsics or the like, and they are unavailable at CT, correct? I suppose that alternative implementations of `btc`, `bts`, `btr`, `bsf` and `bt` could exist that do not use the runtime that could be used if(__ctfe) in the implementation of BitArray, that would make the above code work. Is this feasible? Is there precedent in phobos? Are there complications? https://github.com/ldc-developers/druntime/pull/182

But, keep in mind using array of arrays is not efficient.
For multidimensional arrays use Mir Slices.
If you need more information on how to create matrices, see
this article:

it should be just one call to chunks --> arr.chunks(3), otherwise
you'll get two nested arrays while you need only one. Sorry for
confusion.

Hi.
Is there a Built-in function (no code, only a built-in function)
that transform a linear array to a Matrix?
For example:
From
[10,20,30,40,50,60,70,80,90,100,110,120];
To
[
[10,20,30],
[40,50,60],
[70,80,90],
[100,110,120]

Thank You very much

Anyway, I don't think this fails to work because of an error

cause it, I am glad to know, but thank you for your help.
Well, it is supposed to be a "just works" setup helper, so
anything in it is a problem! There was an off-by-one bug in
the downloader, maybe that missing byte made ldc ignore the
corrupted library file.
I think I managed to get phobos2 and druntime to link. However,
I still get linker errors saying that the following symbols are
undefined: statvfs, fmodl, modfl, getdelim, _tlsend,
__bss_end__, _tlsstart, __libc_current_sigrtmin,
__libc_current_sigrtmax, strtold. I'm not sure what to do about
that; did I forget to link something or are these symbols not
in the Android runtime?
I managed to narrow it down to just one error. The missing
`_tlsstart` and `_tlsend` symbols were because of the missing
`void main() {}`, that used to be added automatically in
d_android v0.0.5 but not in v0.1.0. It worked when I added an
empty main function.
Most of the other errors were because of the API level of
Android; for whatever reason, Android Studio chose API level 16
instead of at least 21, so changing minSdkVersion to 21 in
build.gradle made those errors go away.
However, I still get one undefined reference to __bss_end__, and
I don't know how to fix this. Is this also a problem with TLS or
the API level?
Thanks.
